If approved, the bond measure would go to voters in the May 17 election.

District leaders have said bond money would be used largely for building repairs, plus textbooks and technology updates. Roof replacements at both Tualatin High School and Hazelbrook Middle School have been identified as top priorities.

Other improvements listed in the official summary up for consideration Monday include replacing leaky windows and worn floor coverings, and updating utility systems to make them more energy-efficient. The bond would also fund improved handicapped access at school buildings and constructing a small bus yard, according to the summary.

By moving to a smaller bond measure, the district will put a much less costly request to voters. The $20 bond would cost property owners 8 cents per $1,000 of assessed value, or $16 per year for the owner of a $200,000 home. District officials had said a $25 million bond would have cost taxpayers 39 cents per $1,000 of assessed value.

The taxpayer cost also dropped because the $20 million bond assumes a longer six-year payback, said district spokesperson Susan Stark Haydon. The district has qualified to borrow the first $10 million interest-free.
